APPLICATION OVERVIEW
APPLICATION 03 · VISION MARKING
Vision-guided UDI Laser Marking
Permanent identification, vision compensation, code reading and linked production data
This application covers UDI, Data Matrix and fine-character marking on medical devices and small precision parts, connecting vision, material response, contrast and code verification.
IndustryMedical devices / precision components
MaterialStainless steel, titanium, engineering plastics
ProcessUV / fiber vision-guided marking
VerifyContrast, position, read grade and data
Media & Evidence
Assess the part before selecting equipment
The information is organized around the part, material, target and validation conditions so the critical test items are clear.
EVIDENCEValidation records
Keep before-and-after photos, part conditions, system configuration, inspection method and unresolved boundaries so results remain reviewable.
Application Challenges
What makes this application difficult?
Equipment selection must start with the part and quality target, not laser power or a generic process name alone.
Material and wavelength
Metal, polymers and coatings respond differently to fiber, MOPA and UV; select by target contrast and heat input.
Position and angle compensation
Fixture-free and mixed parts require reliable feature recognition before the mark is corrected.
Closed-loop code quality
A code must be verified at the real reading distance and production speed, not only seen by eye.
Verification Workflow
From samples to equipment configuration
Validate feasibility before freezing tooling, motion and automation scope to reduce custom-project delivery risk.
Define code content
Confirm character size, code rules, serialization and data source.
Test material response
Compare fiber, MOPA and UV for color, depth, heat input and speed.
Establish vision datum
Define field of view, lighting, features, angle compensation and exceptions.
Validate traceability
Test reading, duplicate prevention, database and interface logic at takt.

Application FAQ
Questions before the project starts
How do fiber, MOPA and UV compare?
Compare material absorption, target color, character size, heat sensitivity and takt using representative samples.
Can vision eliminate tooling entirely?
Sometimes, but field of view, occlusion, reflectivity, overlap and height variation still require review.
Can the system connect to MES or a code database?
Yes, after code rules, protocol, read verification and exception handling are defined.
